Borla S-Type Cat-Back Exhaust for 2022-2023 Chevy Silverado 1500 ZR2 & GMC Sierra 1500 AT4X (6.2L) - 140914

Fits 2022-2023 Chevrolet Silverado 1500 ZR2 and GMC Sierra 1500 AT4X (6.2L) with Crew Cab Short Bed (147.5" wheelbase).

The Borla S-Type Cat-Back exhaust system is engineered to provide a deep, aggressive growl for the 6.2L V8 without introducing cabin drone. Constructed from premium T-304 austenitic stainless steel—a material superior to the 400-series steel found in many aftermarket options—this system is built for long-term durability in harsh environments. It features 3.5" primary piping that transitions into dual 2.75" turn down tail pipes, a design that maintains high exhaust velocity while preserving ground clearance for off-road use.

Utilizing Borla's patented straight-through and multi-core technology, this system optimizes exhaust flow to improve performance. The S-Type sound profile offers a balanced, high-performance tone. For owners seeking a more aggressive volume, this system is modular; replacing the secondary muffler with the Polyphonic Harmonizer (part number 60680) converts the sound level to Borla’s louder ATAK configuration. Every system is precision CNC-manufactured with mandrel bends to ensure an exact fit and maximum flow.
